As a part of research studies on the pollution at heavy-oil coated parts of the Sea of Japan coastline, resulting from the wrecked Russian tanker Nakhodka on Jan. 2, the following experiments were performed using three heavy oil samples. Polycyclic aromatic hydrocarbons (PAH) were analyzed by HPLC in the heavy oil that washed ashore, which was collected at Mikuni-cho in Fukui Prefecture on Jan. 16, 1997, heavy oil in the oil compartment of the bow of the tanker, and commercial heavy oil (class C) .<BR>Mutagenicities of the extracts of these oil samples were also measured. The amount of benzo (<I>a</I>) pyrene (BaP) contained in the heavy oil that washed ashore was about a quarter of the average in 51 soil extracted samples, which were collected at an urban area in Tokyo in 1984, and mutagenicity of the extract from the oil was about 4-fold higher than the average in the extracts from the soil samples.
